Specific embodiment

Now, by refer to the attached drawing, exemplary embodiment of the invention is described.

[example 1]

（The configuration of communication system 2）

As shown in figure 1, communication system 2 includes multiple access points（Hereinafter referred to as AP）4a and 4b, multifunction peripheral Equipment（Hereinafter referred to as MFP）10 and portable set 50.At will mention, be included in the multiple AP in communication system 2 Two are not limited to, and can be three or more.

（The type of the radio communication that MFP10 can be carried out）

MFP10 is configured for according to near-field communication（Referred to as NFC）The radio communication of pattern, according to Wi-Fi direct （Referred to as WFD）The radio communication of pattern and the radio communication according to normal Wi-Fi mode.Hereinafter, according to above-mentioned each The radio communication of individual pattern will be referred to as " NFC communication ", " WFD communications " and " normal Wi-Fi communications）.

（NFC communication）

NFC patterns are the wireless communications modes for so-called near-field communication, and are for example based on international standard ISO/ The wireless communications mode of IEC21481 or 18092.MFP10 can carry out NFC communication with portable set 50.

（WFD communicates）

WFD patterns are in " the Wi-Fi equities set up by Wi-Fi Alliance（P2P）It is wireless described in technical specification V1.1 " Communication pattern.WFD patterns are for example for carrying out according to IEEE（It is the abbreviation of Institute of Electrical and Electronics Engineers）'s IEEE802.11 standards and the standard based on IEEE802.11 standards（Such as 802.11a, 802.11b, 802.11g, 802.11n Etc.）Radio communication wireless communications mode.

MFP10 can add WFD networks and with the other equipment on corresponding WFD networks carry out target data WFD lead to Letter.Target data is the data of the information for including the Internet of OSI Reference Model.Target data includes such as print data, sweeps Retouch data etc..

Hereinafter, the equipment for carrying out WFD communications is possible to, such as MFP10 is referred to as " WFD compatible equipments ".In above-mentioned WFD In specification, as the state of WFD compatible equipments, three kinds of states are had been defined for, i.e. group's owner's state（Hereinafter referred to as " G/O states "）, client state and equipment state.WFD compatible equipments can selectively in a state of above-mentioned three kinds of states Middle operation.

When a pair of the WFD compatible equipments set in equipment state need to be formed WFD networks, generally, in corresponding WFD The radio communication of referred to as G/O negotiations is carried out between compatible equipment pair.In G/O negotiations, by the one of corresponding WFD compatible equipments pair It is individual to be defined as G/O states, and another of correspondence WFD- compatible equipments pair is defined as client state.It is set in G/O shapes Equipment in state（Hereinafter referred to as " G/O equipment "）And the equipment set in client state（It is hereinafter referred to as " objective Family end equipment "）Configuration WFD networks.In WFD networks, a G/O equipment and one or more client devices there may be. G/O equipment is configured as managing one or more client devices.Specifically, on each of one or more client devices Individual, G/O equipment carries out the certification of correspondence client device.Then, in G/O equipment in the certification correspondence successful feelings of client device Under condition, in the managing listings that G/O equipment is stored in the memory of G/O equipment, the id information of description correspondence client device（I.e. MAC Address）.And, in the present example, in the WFD networks belonging to MFP10, G/O equipment（That is, MFP10 or different from MFP10 G/O equipment）, the certification of each client device is carried out using certificate scheme " WPA2 " and encipherment scheme " AES ".If objective Family end equipment withdraws WFD networks, then id information of the G/O equipment from managing listings erasing correspondence client device.

G/O equipment can carry out the radio communication of target data with each client device registered in managing listings.So And, on the also unregistered unregistered equipment in managing listings, G/O equipment can carry out the unregistered equipment of correspondence and add WFD The radio communication of the specific data needed for network；However, G/O equipment can not carry out the radio communication of target data.Specific data It is the data of the information of the Internet for not being included in OSI Reference Model, but the data including physical layer, such as probe requests thereby are believed Number（Hereinafter referred to as " PReq signals "）With probe response signal（Hereinafter referred to as " PRes signals ".And, G/O sets The standby radio communication that target data can be relayed between multiple client equipment.

It is not belonging to the WFD compatible equipments of WFD networks（The unregistered unregistered equipment i.e. in the managing listings of G/O equipment） It is the equipment in equipment state.Equipment in equipment state can carry out with G/O equipment add WFD networks necessary to The radio communication of above-mentioned specific data；However, the equipment can not carry out the above-mentioned target data with G/O equipment and client device Radio communication.

As described above, in WFD networks, a WFD compatible equipment communicates to the WFD that can carry out target data, without The intervention of the AP being separately configured with those WFD compatible equipments.That is, WFD communications refer to the radio communication without AP interventions.

At will mention, hereinafter, it is impossible to selectively three kinds of states defined in above-mentioned WFD specifications（That is G/O State, client state and equipment state）A state in operation but radio communication can be carried out via AP（I.e. hereinafter described Normal Wi-Fi communications）Equipment be referred to as " non-WFD compatible equipments "." non-WFD compatible equipments " is referred to as that " tradition sets It is standby ".Equipment in G/O states can describe the id information of non-WFD compatible equipments in managing listings.In this case, non-WFD Compatible equipment can add WFD networks as client device.In the present example, portable set 50 is non-WFD compatible equipments （That is, legacy equipment）.Therefore, in the case where MFP10 is in G/O states, MFP10 can carry out number of targets with portable set 50 According to WFD communicate.

（Normal Wi-Fi communications）

Normal Wi-Fi mode is determined by Wi-Fi Alliance and different from the wireless communications mode of WFD patterns.With WFD moulds Formula is similar to, and normal Wi-Fi mode is and the mark based on IEEE802.11 standards for the IEEE802.11 standards according to IEEE It is accurate（Such as 802.11a, 802.11b, 802.11g, 802.11n etc.）, carry out the wireless communications mode of radio communication.However, As described above, WFD patterns are the wireless communications modes for carrying out the radio communication without AP interventions.On the other hand, normal Wi-Fi Pattern is the wireless communications mode for carrying out radio communication via AP.At this point, WFD patterns and normal Wi-Fi mode It is different from each other.

MFP10 can add normal Wi-Fi network, and be set with any other in corresponding normal Wi-Fi network via AP The standby normal Wi-Fi communications for carrying out target data.In the present example, because portable set 50 is non-WFD compatible equipments（That is, Legacy equipment）, thus it can carry out normal Wi-Fi communications.Therefore, MFP10 can via any one AP of multiple AP4a and 4b, The normal Wi-Fi for carrying out target data with portable set 50 communicates.

In the present example, as the certificate scheme communicated for normal Wi-Fi, it is possible to use Open, WPA（It is Wi-Fi Protect the abbreviation for accessing）With any one in WPA2.In these three certificate schemes, " Open " is with minimum safe Certificate scheme, " WPA " is the certificate scheme with the security higher than " Open ", and " WPA2 " is that have higher than " WPA " The certificate scheme of security.In " Open ", do not carry out using the certification of password.Conversely, in " WPA " and " WPA2 ", carrying out Use the certification of password.

In the present example, as the encipherment scheme communicated for normal Wi-Fi, it is possible to use WEP（It is that Wired Equivalency is protected Close abbreviation）, TKIP（It is the abbreviation of Temporal Key Integrity Protocol）Or AES（It is the abbreviation of Advanced Encryption Standard）. In these three encipherment schemes, " WEP " is the encipherment scheme with minimum safe, and " TKIP " is that have the safety higher than " WEP " Property encipherment scheme, and " AES " be have higher than " TKIP " security encipherment scheme.

Normal Wi-Fi network is the wireless network set up in the environment that can install AP, such as corporate lan, family expenses LAN Deng, and the wireless network for being typically required stabilization formation.On the other hand, WFD networks be for example due to not needing any AP, The wireless network for carrying out temporary wireless communication and setting up between a pair of WFD compatible equipments, is typically required be temporarily formed wireless Network.In this way, in the present example, it is assumed that normal Wi-Fi network is that the wireless network and WFD networks of needs stabilization formation are to need The situation of the wireless network to be temporarily formed.

（The configuration of MFP10）

MFP10 is configured for multiple functions, including printing function and scan function.As shown in figure 1, MFP10 includes Operating unit 12, display unit 14, print unit 16, scanning element 18, wireless LAN interfaces（Hereinafter, term " interface " is used In finger I/F）20th, NFC I/F22 and control unit 30.These parts 12 to 30 are connected to bus line（Without reference to symbol）.

Operating unit 12 has multiple keys.User can operate the operating unit 12 and by various instruction inputs to MFP10. Display unit 14 is configured as showing various information.Printing device 16 is the printer of such as inkjet type mechanism or laser class mechanism Structure.Scanning element 18 is the sweep mechanism of such as CCD or CIS.

WLAN I/F20 is configured as carrying out the interface of WFD communications and normal Wi-Fi communications.WLAN I/F20 It is physically an interface（That is, one IC chip）.However, to WLAN I/F20, assignment can be used for the MAC ground of WFD communications Location（Hereinafter referred to as the MAC Address for WFD）And can be used for the MAC Address of normal Wi-Fi communications（Hereinafter, claim It is the MAC Address for normal Wi-Fi）.Especially, to WLAN I/F20, the MAC ground for normal Wi-Fi is assigned in advance Location.Control unit 30 is different from the MAC Address for normal Wi-Fi to generate using the MAC Address that this is used for normal Wi-Fi , MAC Address for WFD, and the MAC Address of WFD will be used for assign to WLAN I/F20.Therefore, control unit 30 The MAC Address for WFD that communicated using the normal Wi-Fi of the MAC Address for normal Wi-Fi and used can simultaneously be carried out WFD communicates.That is, MFP10 can simultaneously add both WFD networks and normal Wi-Fi network.

Say, WFD communications and normal Wi-Fi communications can be expressed as follows in the MAC Address face that can be used by MFP10.That is, WFD communications are the radio communications of the MAC Address using the WFD for MFP10, and normal Wi-Fi communications are to be used for The radio communication of the MAC Address of the normal Wi-Fi of MFP10.And, WFD networks are the MAC Address using the WFD for MFP10 Wireless network, and normal Wi-Fi network is the wireless network of the MAC Address using the normal Wi-Fi for MFP10.

NFC I/F22 are configured as carrying out the interface of NFC communication.The chip of configuration NFC I/F22, and configuration is wireless It is different from each other on the chip makes physical of LAN I/F20.

Via the traffic rate of the radio communication of WLAN I/F20（The maximum rate of the communication be such as 11Mbps extremely 600Mpbs）It is above the traffic rate of the radio communication via NFC I/F22（The maximum rate of the communication is such as 100Kbps To 424Kbps）.Additionally, the frequency of the carrier wave via the radio communication of WLAN I/F20（The frequency of such as 2.4GHz to 5.0GHz Band）Different from the frequency of the carrier wave of the radio communication via NFC I/F22（The frequency band of such as 13.65MHz）.And, for example, In the case that the distance between MFP10 and portable set 50 are equal to or less than 10cm, control unit 30 can be via NFC I/ F22, NFC communication is carried out with portable set 50.Meanwhile, not only the distance between MFP10 and portable set 50 be equal to or In the case of less than 10cm, and in the case that distance between MFP10 and portable set 50 is equal to or more than 10cm（Most Big distance is e.g., from about 100m）, control unit 30 can via WLAN I/F20, with portable set 50 carry out WFD communicate and Normal Wi-Fi communications.That is, MFP10 can be via WLAN I/F20 and communications destination equipment（Such as portable set 50）Enter The ultimate range of row radio communication carries out the maximum of radio communication more than MFP10 via NFC I/F22 and communications destination equipment Distance.

Control unit 30 includes CPU32 and memory 34.CPU32 is configured as according to the program stored in memory 34 Carry out various treatment.CPU32 can carry out the treatment of the program according to the function of realizing above-mentioned part 41 to 46.Memory 34 by ROM, RAM, hard disk etc. are configured.Memory 34 is configured as the said procedure that storage can be performed by CPU32.

Memory 34 is configured to storage and represents relative to WFD, the WFD state values of the current state of MFP10（I.e. Any one state in G/O states, client state and equipment state）.In the case where MFP10 belongs to WFD networks（That is, WFD state values represent the situation of G/O states or client state）, memory 34 further stored for carrying out WFD communications WFD wireless settings.

WFD wireless settings include certificate scheme information, encipherment scheme information, password, service set identifier（SSID）And base This service set identifier（BSSID）.The SSID being included in WFD wireless settings is the network identifier for recognizing WFD networks. The BSSID being included in WFD wireless settings is the unique identifier of the G/O equipment for assigning to WFD networks（For example, G/O equipment MAC Address）.

Generally, when WFD networks are formed, G/O equipment prepares WFD wireless settings, and corresponding WFD wireless settings are carried Supply each client device.For example, when MFP10 is operated in G/O states, and when forming WFD networks, the control list of MFP10 Unit 30 prepares WFD wireless settings.Specifically, control unit 30 prepares predetermined authentication scheme information（That is, " WPA2 "）Add with predetermined Close scheme information（That is " AES "）.Control unit 30 prepares prescribed password, or prepares password by regenerating password.Control Unit 30 prepares predetermined SSID or regenerates SSID, to prepare SSID.And, control unit 30 prepares for the pre- of WFD MAC Address is determined, as BSSID.

Therefore, in the case where MFP10 is operated in G/O states and belongs to WFD networks, the storage of memory 34 is worked as When MFP10 forms corresponding WFD networks, the WFD wireless settings prepared by MFP10.Meanwhile, in MFP10 in the client state When operating and belong to WFD networks, memory 34 is stored when corresponding G/O equipment forms corresponding WFD networks, by with The WFD wireless settings that MFP10 different G/O equipment prepares（That is, the WFD wireless settings for being obtained from corresponding G/O equipment）.

Additionally, in the case where MFP10 belongs to normal Wi-Fi network, memory 34 further stores normal for carrying out The normal Wi-Fi wireless settings of Wi-Fi communications.Normal Wi-Fi wireless settings generally include certificate scheme information, encipherment scheme letter Breath, SSID, BSSID and password.The SSID being included in normal Wi-Fi wireless settings is for recognizing normal Wi-Fi network Network identifier.The BSSID being included in normal Wi-Fi wireless settings information is to be assigned to the AP to form normal Wi-Fi network Unique identifier（For example, the MAC Address of AP）.

Used as the method for the MFP10 normal Wi-Fi networks of addition, the user that there is MFP10 provides to operating unit 12 The first method of scheduled operation, and the step of carry out Fig. 3 hereinafter described S42 to S48 second method.

In first method, when scheduled operation is provided to operating unit 12, MFP10 carries out SSID search.As a result, from depositing It is each of AP4a around MFP10 and 4b, MFP10 is obtained and represented the current certificate scheme for just being used by corresponding AP Certificate scheme information, the encipherment scheme information for representing the current encipherment scheme for just being used by corresponding AP, and it is current just by right SSID and BSSID that the AP for answering just is being used.Then, MFP10 is controlled so that display unit 14 shows what is obtained from multiple AP Multiple SSID.User selects a SSID using operating unit 12 from multiple SSID（That is, one AP）.

As described above, in the case of using the normal Wi-Fi of high security of certificate scheme " WPA " and " WPA2 ", carrying out Use the certification of password.Therefore, in the case where selected AP just uses certificate scheme " WPA " or " WPA2 ", user also uses behaviour Make unit 12 to input password.MFP10 is not using only certificate scheme information, encipherment scheme information, the SSID obtained from selected AP And BSSID, but also carry out the wireless connection with selected AP using the password by user input.Wireless connection includes MFP10 Add communication process necessary to generally selected network（For example, for the communication process of certification, such as authentication signal, association please Ask the communication of signal and association response signal）.In this way, MFP10 adds the normal Wi-Fi network that selected AP is formed.

Meanwhile, in the case of using the normal Wi-Fi network of low-security of certificate scheme " Open ", do not carry out using close The certification of code.Therefore, in the case where selected AP is just using certificate scheme " Open ", user does not input any password.MFP10 makes Carried out connecting with the wireless of selected AP with the certificate scheme information, encipherment scheme information, SSID and BSSID that are obtained from selected AP Connect, so as to the normal Wi-Fi network for adding selected AP to be formed.Memory 34 is stored for each with the wireless connection of selected AP Individual information（Such as certificate scheme information）, as normal Wi-Fi wireless settings.

As long as MFP adds normal Wi-Fi network by the above method, memory 34 with for recognizing corresponding normal Wi- The SSID of Fi networks and the cryptographic association being just used in corresponding normal Wi-Fi network, storage participate in item of information.That is, store Corresponding one or more participations of device 34 is cumulatively stored with MFP10 is already engaged in one or more normal Wi-Fi networks Item of information.And, as described above, in using the normal Wi-Fi network of certificate scheme " Open ", any password is not used.Cause This, the participation item of information corresponding with that normal Wi-Fi network includes SSID, but does not include any password.

Even if in above-mentioned second method, the step of Fig. 2 in S42, the SSID that MFP10 is discussed in detail below is searched Rope.Then, in step S44, MFP10 automatically selects a SSID（That is, one AP）, the finger without receiving any user Order.Then, in step S48, MFP10 carries out the radio communication with selected AP.In this way, MFP10 be automatically added by The normal Wi-Fi network for selecting AP to be formed.

（The configuration of portable set 50）

Portable set 50 is such as such as mobile phone（Such as smart phone）, it is PDA, notebook PC, tablet PC, portable The portable terminal of formula audio player or portable video player.Portable set 50 can carry out NFC communication and just Normal Wi-Fi communications.

Portable set 50 includes that operating unit 52, display unit 54, WLAN I/F60, NFC I/F62 and control are single Unit 70.These parts 52 to 70 are connected to bus line（Without reference symbol）.Operating unit 52 has multiple keys.User can operate The operating unit 52 is by various instruction inputs to portable set 50.Display unit 54 is configured as showing various information.

WLAN I/F60 is the interface for carrying out normal Wi-Fi communications.NFC I/F62 are for carrying out NFC communication Interface.The difference between difference and the interface 20 and 22 of MFP10 between these interfaces 60 and 62 is identical.That is, for example, via Traffic rate of the traffic rate of the radio communication of WLAN I/F60 higher than the radio communication via NFC I/F62.

Control unit 70 includes CPU72 and memory 74.CPU72 is configured as according to the journey stored in memory 74 Sequence, carries out various treatment.The program stored in memory 74 is included for being controlled so that MFP10 carries out various functions （Such as printing function and scan function）Application 76.For example, can pacify from the server provided by the seller of MFP10 using 76 It is attached in portable set 50, or can be installed in portable set 50 from the medium transported with MFP10.CPU72 can basis Processed to realize the function of those parts 81 to 86 using 76.And, the example 4 to 6 that part 81 to 86 is described below In work.

（The configuration of AP4a and 4b）

Each of AP4a and 4b is not the G/O equipment of WFD, but referred to as WAP or wireless/lan router Normal AP.Each of AP4a and 4b form normal Wi-Fi network.Each of AP4a and 4b are subordinated to normal Wi-Fi network Multiple equipment in an equipment（Such as portable set 50）Target data is received, and corresponding target data is transmitted To the second equipment in above-mentioned multiple equipment（Such as MFP10）.That is, each of AP4a and 4b are served as and are belonging to normal Wi-Fi The trunking of the radio communication of target data is relayed between a pair of equipment of network.

By the way, the G/O equipment and normal AP of WFD（That is AP4a or 4b）Between difference it is as follows.That is, the G/O of WFD Equipment is being withdrawn WFD networks and is rejoining the different state of G/O states of another WFD networks from corresponding equipment（It is i.e. objective Family end state）Middle operation.On the other hand, even if corresponding AP forms normal Wi-Fi network, each normal AP can be also carried out one Function to forwarding radio communication between equipment.That is, normal AP is only capable of operated with the identical in the G/O states of WFD, but Can not carry out being operated with the identical in the client state of WFD.

（The application treatment of the portable set 50 shown in Fig. 2）

Then, with reference to Fig. 2, the control unit 70 of portable set 50 will be described according to using in 76 treatment for carrying out Hold.Want to be controlled so that MFP10 printings are by the printing mesh of the storage in portable set 50 in the user of portable set 50 Mark data（Hereinafter referred to as " print data "）During the image of expression, user operates the operating unit 52 and activates and applies 76. As a result, control unit 70 starts the flow chart of Fig. 2 according to applying 76.

User provides printing to operating unit 52, including for selecting to be deposited in the memory 74 of portable set 50 The operation of the print data of storage and the operation for being used to determine whether to print data setting code.In this case, control Unit 70 is defined as "Yes" in step slo, and enters step S11.

By the way, in the case of to print data setting code, the operating unit 12 of MFP10 is operated except non-user And by corresponding Password Input to MFP10, MFP10 does not start the printing according to print data.That is, printing is had been given by User be only capable of obtain by MFP10 printing produce printed matter.On the other hand, any password is not being set to print data In the case of, MFP10 immediately begins to printing after print data is received（That is, even if not being input into any password to MFP10, MFP10 also begins to printing）.That is, the printing can be obtained with anyone outdoor except provide printing to portable set 50 Product.Therefore, in the case of to print data setting code, print data it is safe in not to print data set it is any Security in the case of password.

In step s 11, first, the generation of control unit 70 NFC information, including：For indicating MFP10 to carry out printing function Print command, and represent print data security safety information.NFC information does not include print data.And, In the case that user is determined to print data setting code, the generation of control unit 70 represents the safety information of safety.This In the case of, safety information further includes to be set to the password of the print data.Meanwhile, determine not to print data in user In the case of setting any password, the generation of control unit 70 indicates the safety information without safety.In this case, security Information does not include password.

In the case of the power on of MFP10, the NFC I/F22 of MFP10 are transmitted and can be carried out NFC communication for detection Equipment（That is portable set 50）Detection radio wave.After above-mentioned printing is carried out, the user of portable set 50 will Portable set 50 is carried near MFP10.Therefore, the distance between portable set 50 and MFP10 become less than theirs Radio wave reaches mutual distance（Such as 10cm）.In this case, portable set 50 receives detection wirelessly from MFP10 Electric wave and will response radio wave transmissions to MFP10.As a result, in step s 12, control unit 70 using NFC sessions come by The NFC information for being generated is transferred to MFP10 via NFC I/F62.

When NFC information is transferred into MFP10 from portable set 50, MFP10 S30 the step of Fig. 3 described below In be defined as "Yes", and carry out the treatment of step S32 and subsequent step.As a result, MFP10 using NFC sessions come WFD is wireless Set（The step of Fig. 3 S40）With AP information（The step of Fig. 3 S46）It is transferred to portable set 50.WFD wireless settings include working as The preceding various information just used in MFP10 is just with the WFD networks residing for G/O stastus formats（That is, certificate scheme information, encryption Scheme information, SSID, BSSID and password）.AP information is each including what is currently just used in the normal Wi-Fi network that AP is formed The information of kind（Authentication authorization and accounting scheme information, encipherment scheme information, SSID, BSSID）.It may be mentioned that in corresponding normal Wi-Fi nets In the case of the certification using password is carried out in network, i.e. the certificate scheme being currently using in corresponding normal Wi-Fi network In the case of " WPA " or " WPA2 ", AP information further include currently used in corresponding normal Wi-Fi network it is close Code.Meanwhile, in the case of the certification using password is not carried out in corresponding normal Wi-Fi network, i.e. corresponding normal In the case that the certificate scheme being currently using in Wi-Fi network is " Open ", AP information does not include password.

The step of Fig. 2 in S14, the control unit 70 of portable set 50 receives WFD via NFC I/F62 from MFP10 Wireless setting or AP information.After WFD wireless settings or AP information are received in the step S14, control unit 70 be controlled so as to Pre- tone for example is exported from portable set 50, the user's NFC communication for informing portable set 50 has terminated.Cause This, user can appreciate that can make portable set 50 away from MFP10.At the end of step S14, control unit 70 enters step S16。

In step s 16, control unit 70 carries out wireless connection according to the information received in step S14.In step The information received in S14 in the case of WFD wireless settings, WFD wireless setting of the control unit 70 received by come through By WLAN I/F60 wireless connection is carried out with the MFP10 in G/O states.Corresponding wireless connection is included for adding MFP10 is just with the communication process of the specific WFD networks residing for G/O stastus formats（For example, for the communication process of certification）.Cause This, portable set 50 can be used as in the client device above-mentioned specific WFD networks of participation.As a result, MFP10 and portable set 50 Belong to same WFD networks.

Meanwhile, in the case that the information received in step S14 is for AP information, control unit 70 uses received AP to believe Breath comes via WLAN I/F60, and wireless connection is carried out with AP.Corresponding wireless connection includes being connect by being included in for addition The communication process of the specific normal Wi-Fi network of the SSID identifications in the AP information of receipts（For example for the communication process of certification）. Therefore, portable set 50 can participate in above-mentioned specific normal Wi-Fi network.As a result, MFP10 and portable set 50 belong to same Normal Wi-Fi network.

And, when step S16 is carried out, portable set 50 already belongs to the situation of WFD networks or normal Wi-Fi network Under, in step s 16, control unit 70 is withdrawn existing network and adds above-mentioned specific WFD networks or specific normal Wi-Fi nets Network.Additionally, in the case where above-mentioned existing network is withdrawn, control unit 70 is by for rejoining the wireless of above-mentioned existing network Set（Such as SSID, password etc.）Storage is in memory 74.

When step S16 terminates, in step S20, control unit 70 passes print data via WLAN I/F60 It is sent to MFP10.For example, in the case where portable set 50 participates in above-mentioned specific WFD networks, in step S20, control unit 70 MFP10 for being in G/O states print data to be sent to using above-mentioned specific WFD networks.That is, even if trunking （Such as AP4a or 4b）In the case of not relaying print data, print data can be also transferred directly to from portable set 50 MFP10.And, for example, in the case where portable set 50 participates in above-mentioned specific normal Wi-Fi, in step S20, control Unit 70 using above-mentioned specific normal Wi-Fi network come by print data via AP（Such as 4a）It is sent to MFP10.

When step S20 terminates, the application treatment of Fig. 2 terminates.And, portable set 50 is withdrawn existing in step s 16 In the case of having network, when step S20 terminates, control unit 70 withdraws the new net that control unit 70 is added in step s 16 Network and by using in step s 16, the wireless setting stored in memory 74 adds legacy network again.Meanwhile, In the case that portable set 50 does not withdraw existing network in step s 16, even if step S20 terminates, control unit 70 keeps Portable set 50 participates in the state of above-mentioned new network.

（The communication process of the MFP10 shown in Fig. 3）

Then, the content of the treatment that the control unit 30 of MFP10 is carried out with reference to Fig. 3, will be described.As described above, Fig. 2's In step S12, NFC information is sent to MFP10 from portable set 50.The receiving unit 41 of MFP10 via NFC I/F22, NFC information is received from portable set 50.In this case, receiving unit 41 is defined as "Yes" the step of Fig. 3 in S30, And communication process enters step S32.

In step s 32, the first determining unit 47 determines whether the current state of MFP10 is G/O states（That is, MFP10 is It is no to be operated in G/O states and belong to WFD networks）.The WFD state values stored in memory 34 represent the feelings of G/O states Under condition, the first determining unit 47 is defined as "Yes" in step s 32, and communication process enters step S34.Meanwhile, in storage In the case that the WFD state values stored in device 34 represent client state or equipment state, the first determining unit 47 is in step S32 It is defined as "No", and communication process enters step S36.

In step S34, the first determining unit 47 determines to belong to MFP10 just with the WFD networks residing for G/O stastus formats Whether client device number is equal to predetermined maximum N.Here, N can be 1, or the integer equal to or more than 2.Set in client In the case that standby number is equal to maximum N, the first determining unit 47 is defined as "Yes" in step S34, and communication process enters Step S41.Meanwhile, in the case where client device number is less than maximum, the first determining unit 47 is defined as in step S34 "No", and communication process enters step S40.

In step S36, the first determining unit 47 determines whether the current state of MFP10 is client state（That is, Whether MFP10 operates in client state and belongs to WFD networks）.The WFD state values stored in memory 34 represent visitor In the case of the state of family end, the first determining unit 47 is defined as "Yes" in step S36, and communication process enters step S41. Meanwhile, in the case that the WFD state values stored in memory 34 represent equipment state, i.e. MFP10 is not belonging to WFD networks In the case of, the first determining unit 47 is defined as "No" in step S36, and communication process enters step S38.

In step S38, form unit 49 and MFP10 is switched to autonomous G/O patterns.As described above, work as re-forming WFD During network, generally, G/O negotiations are carried out, thereby determine that G/O equipment and client device.On the other hand, in autonomous G/O patterns, Determine that MFP10 is in G/O states, without carrying out G/O negotiations.In the stage of step S38, MFP10 is G/O equipment, and is not had There is client device.That is, form unit 49 and form only G/O equipment（That is MFP10）Affiliated WFD networks.Autonomous G/O patterns are to make MFP10 is maintained at the pattern operated in G/O states.For example, being changed into G/O states in G/O negotiations in MFP10 and forming WFD In the case of network, if the WFD networks that client device is answered from team disappear, MFP10 is transformed into equipment state from G/O states （I.e. WFD networks disappear）.On the other hand, for example, being changed into G/O states in autonomous G/O patterns in MFP10 and forming WFD nets In the case of network, even if client device disappears, MFP10 also keeps G/O states（That is, MFP keeps WFD networks）.

In step S38, the WFD wireless settings that unit 49 prepares to need to be used in WFD networks are formed（Authentication authorization and accounting scheme is believed Breath, encipherment scheme information, SSID, BSSID and password）.Have already described above to form the side that unit 49 prepares WFD wireless settings Method.In step S38, additionally, the WFD wireless settings for forming the WFD state values that would indicate that G/O states of unit 49 and being prepared are deposited Storage is in memory 34.When step S38 terminates, communication process enters step S40.

In step s 40, the WFD wireless settings that transmission unit 42 will be stored in memory 34 are passed via NFC I/F22 It is defeated to portable set 50.As described above, in the case of being "No" in step S34, or be the situation of "No" in step S36 Under（I.e. by the situation of step S38）, carry out the treatment of step S40.In the case of being "No" in step S34, belong to MFP10 Maximum is just less than with the client device number of the WFD networks residing for G/O stastus formats.Therefore, it can be controlled so as to just Portable device 50 adds WFD networks as client device.And, in the case where step S36 is "No", in step S38, Formation only exists in the WFD networks belonging to the MFP10 of G/O states.Therefore, it can be controlled so that portable set 50 is used as visitor Family end equipment adds WFD networks.In step s 40, for be controlled so as to portable set 50 as client device add WFD networks, portable set 50 is transferred to by WFD wireless settings from MFP10.When step S40 terminates, communication process enters step Rapid S50.

Meanwhile, in the case where step S34 is "Yes", or in the case where step S36 is "Yes", carry out step S41. In step S41, the second determining unit 48 determines whether MFP10 currently participates in normal Wi-Fi network.Deposited in it there is memory 34 In the case of the normal Wi-Fi wireless settings of storage, the second determining unit 48 is defined as "Yes", and communication process in step S41 Into step S49.Meanwhile, in the case of the normal Wi-Fi wireless settings stored in no memory 34, the second determining unit 48 are defined as "No", and communication process enters step S42.

In step S49, transmission unit 42 prepares and the AP being included in the current affiliated normal Wi-Fi networks of MFP10 （The AP of wireless connection is set up with MFP10）Relevant AP information.Specifically, transmission unit 42 prepares to be included in memory The AP information of the normal Wi-Fi wireless settings stored in 34.Then, the AP information that transmission unit 42 will be prepared is via NFC I/ F22 is transferred to portable set 50.Therefore, portable set 50 in S16, normal Wi- is added by AP information the step of Fig. 2 Fi networks.As a result, MFP10 and portable set 50 belong to the normal Wi-Fi network of identical.When step S49 terminates, mailing address Reason enters step S50.

Meanwhile, in the case where step S41 is "No", carry out the treatment of step S42 to S48.It is "Yes" in step S34 In the case of, belong to MFP10 and maximum N is equal to the client device number of the WFD networks residing for G/O stastus formats.Therefore, can not Portable set 50 can be entered to exercise and add WFD network-based controls as client device.And, it is the feelings of "Yes" in step S36 Under condition, the MFP10 in client device belongs to another equipment with the WFD networks residing for G/O stastus formats.In such case Under, MFP10 is without being controlled so as to another equipment（That is portable set 50）Add the authority of corresponding WFD networks.Cause This, it is impossible to enter to exercise portable set 50 and add WFD network-based controls as client device.Additionally, being in step S41 In the case of "No", MFP10 is currently not involved in any normal Wi-Fi network.Therefore, MFP10 can not be carried out so that portable set Standby 50 controls for adding the current normal Wi-Fi networks for participating in of MFP10.Therefore, in step S42 to S48, control unit 30 is entered Exercise MFP10 and portable set 50 adds the treatment of same normal Wi-Fi network.

As described above, in the present example, if can enter to exercise portable set 50 adds WFD network-based controls（Step S34 is "No", or step S36 is "No"）, then in step s 40, carry out for making portable set 50 add WFD networks Treatment.Therefore, it can that portable set 50 is inserted the WFD networks being temporarily formed.In this case, due to normal Wi- Fi wireless settings are not transferred to portable set 50, it is possible to suppress the security of the normal Wi-Fi network of stabilization formation Reduce.In view of these situations, in this example, first, in step S32 to S40, insert WFD nets by portable set 50 first Network.If impossible, in step S41 to S49, portable set 50 is set to add normal Wi-Fi network.

In step S42, communication obtaining unit 44 carries out SSID search to search for MFP10 existing AP nearby.Due to Communication obtaining unit searches for AP as described above, therefore, communication obtaining unit 44 is referred to as search unit.Communication obtaining unit 44 transmit PReq signals via WLAN I/F20.Once receive PReq signals, existing AP4a and 4b around MFP10 from MFP Each PRes signals are sent to MFP10.Communication obtaining unit 44 via WLAN I/F20, from the every of AP4a and 4b One reception PRes signal.I.e., in the present example, communication obtaining unit 44 can be searched for by SSID, find two AP4a and 4b.

Incidentally, if there is any G/O equipment around MFP10, received from MFP10 in corresponding G/O equipment In the case of PReq signals, PRes signals are also sent to MFP10 by corresponding G/O equipment.Therefore, the obtaining unit 44 that communicates is not only From AP4a and 4b, and can receive PRes signals from G/O equipment.However, in the present example, there is no G/O to set around MFP10 On standby example, will carry out described below.

PRes signals include current SSID, the current certification for just being used by corresponding AP of expression for just being used by corresponding AP The certificate scheme information of scheme, the encipherment scheme information for representing the current encipherment scheme for just being used by corresponding AP, and expression The communication rate information of the traffic rate of the radio communication that corresponding A P is realized.Therefore, communication obtaining unit 44 is by from corresponding AP receives PRes signals, obtains the information relevant with the radio communication using AP.

In step S44, select unit 43 selects an AP from multiple AP4a and 4b.As described above, memory 34 is Store one or more corresponding with one or more normal Wi-Fi networks that MFP10 is already engaged in and participate in item of information.From The multiple SSID in the multiple PRes signals obtained in step S42 are included in, select unit 43 is extracted and is included in memory 34 One or more of middle storage participate in one or more SSID of one or more SSID matchings in item of information.Then, select Unit 43 selects a SSID from one or more SSID for being extracted, to select an AP.Hereinafter, will retouch in detail State for selecting a specific method of AP.

In step S46, transmission unit 42 prepares the AP information relevant with selected AP first.Specifically, transmission unit 42 Prepare from the SSID of step S42 search in selected AP obtain certificate scheme information, encipherment scheme information, SSID and BSSID.And, transmission unit 42 reads the participation item of information of the SSID for including obtaining from selected AP, Yi Ji from memory 34 In the case that corresponding participation item of information includes password, transmission unit 42 prepares correspondence password.Then, transmission unit 42 will include The AP information of the item of information for being prepared is transferred to portable set 50 via NFC I/F22.

In step S48, communication unit 46 uses the single item of information prepared in step S46, via WLAN I/F20 carries out the wireless connection with selected AP.Corresponding wireless connection is included for adding the SSID by preparing in step S46 The communication process of the specific normal Wi-Fi network of identification.In this way, MFP10 can add above-mentioned specific normal Wi-Fi nets Network.As described above, S16 the step of Fig. 2 of portable set 50 adds above-mentioned specific normal Wi-Fi network.As a result, MFP10 and Portable set 50 belongs to the normal Wi-Fi network of identical.When step S48 terminates, communication process enters step S50.

In step s 50, communication unit 46 receives print data via WLAN I/F20 from portable set 50.Example Such as, the step of being carried out after step S40 in S50, communication unit 46 directly connects from the portable set 50 in client state Print data is received, and not via trunking.And, for example, in carrying out step S50 after step S48 or S49, communication unit 46 receive print data via AP from portable set 50.

Then, in step S52, the treatment print data of control unit 30（For example, it is treatable to be processed into print unit 16 Data）And handled data are supplied to print unit 16.Therefore, print unit 16 is carried out according to handled data Print in print media.And, the safety information in including the NFC information for receiving in step s 30 represents safe In the case of, the Password Input in user is included within corresponding safety information to MFP10, do not open by print unit 16 Begin to print（That is, print unit retains printing）.Meanwhile, the safety information in including the NFC information for receiving in step s 30 Represent under unsafe condition, print unit 16 immediately begins to printing after processing data is obtained from control unit 30.Work as step When S52 terminates, the communication process of Fig. 3 terminates.And, the situation of new normal Wi-Fi network is added in step S48 in MFP10 Under, even if step S52 terminates, control unit 30 also keeps MFP10 to participate in the state of above-mentioned new normal Wi-Fi network.

Print data has more than the information transmitted by NFC（NFC information as described above, WFD wireless settings, AP information Etc.）Size of data.As described above, the traffic rate that the traffic rate of NFC communicates less than WFD or normal Wi-Fi communicates.Cause This, is if being used to be carried out between MFP10 and portable set 50 configuration of the radio communication of print data using NFC, Take a long time to carry out the radio communication of print data.In view of these situations, in the present example, MFP10 carries out the step of Fig. 3 Rapid S40, S46 or S49, and by WFD wireless settings or AP information transfers to portable set 50.Therefore, MFP10 and portable Equipment 50 by WLAN I/F20, can carry out the WFD communications or normal Wi-Fi communications of print data, thus, it is possible to rapidly enter The radio communication of row print data.

As described above, portable set 50 be in for carry out with the direct wireless communication of MFP10 and stay out of relaying The AD HOC of equipment（That is MFP10 is in G/O states and portable set 50 is in the pattern of client state）In and In the case of WFD networks can be added（That is the step of Fig. 3, S34 was the situation of "No", or the situation for carrying out step S38）, in step In S40, MFP10 will enable that portable set 50 adds the wireless setting of WFD networks to be transferred to portable set 50.Together When, in the case of can not adding WFD networks when portable set 50 is in above-mentioned AD HOC（That is, the step of Fig. 3, S34 was The situation of "Yes", or step S36 is the situation of "Yes"）, in step S46 or S49, MFP10 will enable portable set 50 The wireless setting of normal Wi-Fi network is enough added to be transferred to portable set 50.Therefore, MFP10 can be according to portable set 50 Whether WFD networks can be added during in above-mentioned AD HOC, appropriate wireless setting is transferred to portable set 50.Therefore, MFP10 suitably can enter to exercise the control that portable set 50 adds WFD networks or normal Wi-Fi network.As a result, MFP10 energy The nothing with the print data of portable set 50 is suitably carried out in step s 50 using WFD networks or normal Wi-Fi network Line communicates.

（Example 1-1）

Then, by the content of the AP selection treatment of S44 the step of describing Fig. 3.In step S44, first, on being extracted One or more SSID each, select unit 43 verifies the current encipherment scheme for just being used by AP first, and the AP is right Answer the source of SSID（It is included in the encipherment scheme information in the PRes signals including correspondence SSID）.Therefore, it is being included in NFC information In safety information represent safety in the case of, i.e., safety information include password in the case of, select unit 43 determines Print data it is safe.In this case, select unit 43 select a SSID, to select an AP, via The SSID confirms encipherment scheme " AES ".Meanwhile, in the case where the safety information being included in NFC information represents unsafe condition, That is, in the case that safety information does not include password, select unit 43 determines that the security of print data is low.In such case Under, select unit 43 selects a SSID to select an AP, confirms the encipherment scheme in addition to " AES " via the SSID （Such as " TKIP " or " WEP "）.

It may be mentioned that in the case where the safety information being included in NFC information represents safety, if there is no The SSID of " AES " is confirmed via it, then select unit 43 can select to have thereby confirmed that the encipherment scheme in addition to " AES " SSID.In the case where the safety information being included in NFC information represents unsafe condition, if without being removed via its confirmation The SSID of " AES " encipherment scheme outward, then select unit 43 can select via its confirm " AES " SSID.That is, carried In the case of the SSID of condition is not met in one or more SSID for taking, select unit 43 can use preordering method（Example Such as random choice method）To select SSID.Even this point is also identical in following examples.

（The specific example of the example 1-1 shown in Fig. 4）

Then, the specific example of example 1-1 with reference to Fig. 4, will be described.In fig. 4, between MFP10 and portable set 50 Single lined arrows represent radio communication via NFC I/F22 and 62, and the two-wire arrow between MFP10 and portable set 50 Head is represented via the radio communication of WLAN I/F20 and 60.AP4a be currently using SSID " aaa ", encipherment scheme " AES " with And certificate scheme " WPA2 ", and realize the traffic rate of 100Mbps.AP4b is currently using SSID " bbb ", encipherment scheme " TKIP " and certificate scheme " WPA ", and realize the traffic rate of 10Mbps.And, currently just used by AP4a and 4b BSSID is not shown in fig. 4.

And, in fig. 4, MFP10 is in G/O states, and forms WFD networks.However, MFP10 has maximum client Hold number N so that portable set 50 can not add WFD networks.And, MFP10 can not currently participate in any normal Wi-Fi nets Network.MFP10 has been added to the normal Wi-Fi network that the normal Wi-Fi network and AP4b of AP4a formation are formed.Therefore, MFP10 Memory stored participation item of information and with the AP4b corresponding participation item of information corresponding with AP4a.

After NFC information is received from portable set 50 via NFC I/F22（The step of Fig. 3, S30 was "Yes"）, MFP10 determines that step S32 is that "Yes" and step S41 are "No" for "Yes", step S34, and SSID is carried out in step S42 Search.Then, each the reception PRes signal of MFP10 from AP4a and 4b.

Under the situation " A " of Fig. 4, the safety information being included in NFC information represents safety.Therefore, in step S44 In, MFP10 is currently using the AP4a of encipherment scheme " AES " from multiple AP4a and 4b selections.Then, in step S46, The AP information for including the SSID " aaa " for representing AP4a is transferred to portable set 50 by MFP10 via NFC I/F22.Then, exist In step S48, MFP10 carries out the wireless connection with AP4a so as to the normal Wi-Fi network for adding AP4a to be formed.

Similarly, the step of Fig. 2 in S16, portable set 50 is also carried out the wireless connection with AP4a to add The normal Wi-Fi network that AP4a is formed.Then, in step S20, portable set 50 will be printed via WLAN I/F60 Data transfer is to AP4a.Print data is transferred to MFP10 by AP4a.As a result, MFP10 the step of Fig. 3 in S50 via wireless LAN I/F20 receive print data and are printed in step S52.

Meanwhile, under the situation " B " of Fig. 4, the safety information being included in NFC information represents dangerous.Therefore, in step In rapid S44, MFP10 is currently using the AP4b of encipherment scheme " TKIP " from multiple AP4a and 4b selections.Then, in step S46 In, the AP information for including the SSID " bbb " for representing AP4a is transferred to portable set 50 by MFP10 via NFC I/F22.With Afterwards, in step S48, MFP10 and AP4b carries out wireless connection so as to the normal Wi-Fi network for adding AP4b to be formed.Therefore, MFP10 receives print data in S50 the step of Fig. 3 via WLAN I/F20, and is printed in step S52.

As described above, in the present example, in the case where the user of portable set 50 is to print data setting code, That is, print data it is safe in the case of（It is an example of the target data with the first safe level）, selection Unit 43 selects just to use an AP of high security encipherment scheme " AES ".Therefore, according to high security encipherment scheme " AES " Carry out the high security communication of print data.That is, MFP10 can be according to the intention of the user of portable set 50（That is high safety Property）, select appropriate AP.

Meanwhile, in the case where the user of portable set 50 does not set any password to print data, i.e. in printing number According to security it is low in the case of（One example of the target data with the second safe level）, select unit 43 selects just to use Low-security encipherment scheme（Such as " TKIP " or " WEP "）An AP.Therefore, according to low-security encipherment scheme, beaten The low-security communication of printing evidence.Because the user of portable set 50 is intended that low-security, therefore, even if using low peace Full property encipherment scheme also has no problem.If unrelated using the security level with print data, it is necessary to select high security to encrypt The configuration of the AP of scheme " AES ", then adding the number of devices of the normal Wi-Fi formed by AP increases, thus the load of corresponding AP Increase.That is, if in the case of using needing the low-security for carrying out print data to communicate, selection is just encrypted using high security The configuration of scheme " AES ", can probably disturb need with corresponding AP carry out high security data communication client device it is logical Letter.In the present example, portable set 50 user be intended that low-security in the case of, using selection just use low peace The configuration of the AP of full property encipherment scheme.Therefore, it can suitably suppress the only one AP in multiple AP4a and 4b has big load Event occur.

（Corresponding relation）

MFP10 and portable set 50 are respectively the examples of the first communication equipment and the second communication equipment.NFC I/F22 and WLAN I/F20 is respectively the example of first kind interface and Second Type interface.G/O states and client state are respectively Major state and the example from state.WFD networks and normal Wi-Fi network be respectively first kind wireless network and Second Type without The example of gauze network."No" situation in the step of Fig. 3 S34, or it is the example of first kind situation to carry out the situation of step S38 Son.The step of Fig. 3 S34 "Yes" situation or step S36 in "Yes" situation be Second Type situation example.In the step of Fig. 3 The wireless setting transmitted in rapid S40 and the wireless setting difference being included in the AP information that will be transmitted in step S46 or S49 It is the example of the first wireless setting and the second wireless setting.Multiple AP4a and 4b are the examples of multiple trunkings.Print data It is the example of target data.PRes signals are the examples of related communications.According to whether setting any password to print data Safety information be related data information and associated processing intelligence example.And, in the example in fig. 4, " AES " and " TKIP " is the example of the first encipherment scheme and the second encipherment scheme.

（Example 1-2）

Other examples 1-2 to 1-9 will be described with reference to Fig. 5.Each of example 1-2 to 1-9 is in the difference of example 1-1 The content of the step of place is Fig. 3 S44.

In example 1-2, the step of Fig. 3 in S44, first, each on one or more SSID for being extracted, Select unit 43 verifies the current authentication signal for just being used by corresponding SSID sources（It is included in the PRes letters including correspondence SSID Certificate scheme information in number）.Then, in the case where the safety information being included in NFC information represents safety, selection is single The selection of unit 43 has confirmed a SSID of " WPA2 " via it, to select an AP（In the example in fig. 4, it is currently using The AP4a of " WPA2 "）.Meanwhile, in the case where the safety information being included in NFC information represents unsafe condition, select unit 43 Selection is via its certificate scheme of the confirmation in addition to " WPA2 "（Such as " WPA " or " Open "）A SSID, to select one Individual AP（In the example of Fig. 4, the AP4b of " WPA " is currently using）.

In the present example, according to high security certificate scheme " WPA2 ", the logical of the print data with high security is carried out Letter（It is an example of the target data with the first safe level）.That is, meanings of the MFP10 according to the user of portable set 50 Figure（That is high security）, select an appropriate AP.And, in the feelings for being intended that low-security of the user of portable set 50 Under condition, i.e. in the case where the communication of the print data with low-security is carried out（It is the number of targets with the second safe level According to an example）, the positive AP using low-security certificate scheme of MFP10 selections.Therefore, it can suitably suppress only some AP The generation of the event with big load.And, in the present example, " WPA2 " and " WPA " is respectively the first certificate scheme and The example of two certificate schemes.

（Example 1-3）

In example 1-1, the user of portable set 50 makes to operating unit 52 and being used to determine whether to print data The operation of password is set.Then, according to corresponding determination, the generation safety information of portable set 50.Instead of this, in example 1- In 3, the user of portable set 50 makes the operation for being used to determine whether encrypted print data to operating unit 52.

In first example, it is assumed that MFP10 and portable set 50 have the situation of public key.Determine encrypted print in user In the case of data, the control unit 70 of portable set 50 carrys out encrypted print data using public key, and MFP10 control list Print data is decrypted using public key by unit 30.Meanwhile, in the case where user determines not encrypted print data, portable set 50 Control unit 70 do not encrypt the print data.

And, in second example, it is assumed that the data form of print data is PDF（It is the contracting of portable document format Write）Situation.In the case where user determines to encrypt the print data, the control unit 70 of portable set 50 uses predetermined electricity Son signs to encrypt the print data and prepare the PDF print datas with the signature.Then, when the control unit of MFP10 30 from portable set 50 receive print data when, control unit 30 is decrypted with the signature using predetermined electronic signature PDF print datas.Meanwhile, in the case where user determines not encrypting the print data, the control unit 70 of portable set 50 The print data is not encrypted（I.e. control unit 70 prepares normal PDF print datas）.

In both above-mentioned first and second examples, with determine do not encrypt the print data situation compared with, it is determined that plus In the case of the close print data, the security of print data is higher.The step of Fig. 2 in S11, the control of portable set 50 It is determined that in the case of encrypted print data, generation represents the safety information of safety to unit 70, and it is determined that not encrypting this In the case of print data, generation represents unsafe safety information.This point is different from example 1-1.Other main points and example Sub- 1-1 is identical.

Even if in the present example, it is also possible to realize and example 1-1 identical effects.And, in the present example, according to whether The safety information of encrypted print data is the example of related data information and associated processing intelligence.

（Example 1-4）

It is similar with example 1-3 in example 1-4, according to whether encrypted print data, determines safety information.And, with Example 1-2 is similar to, and in the case where safety information represents safety, select unit 43 selects just to use an AP of " WPA2 ", And in the case where safety information represents unsafe condition, an AP of the positive certificate scheme using in addition to " WPA2 " of selection.I.e. Make in the present example, it is also possible to realize and example 1-2 identical effects.

（Example 1-5）

In example 1-5, the step of Fig. 2 in S11, the generation of control unit 70 of portable set 50 includes representing printing NFC information of the size information of the size of data of data rather than safety information.And, the step of Fig. 3 in S44, first, Each on one or more SSID for being extracted, select unit 43 is verified answers the AP in the source of SSID to be realized as enlightening Europe Traffic rate（That is, communication rate information is included in the PRes signals including correspondence SSID）.Then, NFC letters are being included in In the case that size information in breath is equal to or more than predetermined threshold, select unit 43 select via its confirm 100Mbps or One SSID of bigger traffic rate（I.e. one AP）.Meanwhile, the size information in NFC information is included in is less than predetermined threshold In the case of value, select unit 43 selects a SSID via its traffic rate of the confirmation less than 100Mbps（I.e. one AP）.

In the present example, in the case where the size of data of print data is big, of traffic rate high is realized in selection AP.It is thereby possible to reduce the time needed for print data of the transmission with big size of data.Meanwhile, in the number of print data In the case of being small according to size, an AP of low communication speed is realized in selection.Because the size of data of print data is small, so Even if using low communication speed, the time needed for transferring printing data also will not be elongated.If using the number regardless of print data According to size, it is necessary to which the configuration of the AP of traffic rate high is realized in selection, then the load of corresponding AP increases.That is, if using needs In the case of carrying out the transmission of the print data with small size of data, the configuration of the AP of traffic rate high is realized in selection, then Probably interference needs the communication of the client device of the communication that large data is carried out with corresponding AP.According to this example, Ke Yishi Locality suppresses the generation that only some AP have the event of big load.

（Example 1-6）

In example 1-6, the step of Fig. 2 in S11, the generation of control unit 70 of portable set 50 includes representing printing NFC information of the format information of the data form of data rather than safety information.And, the step of Fig. 3 in S44, in bag Include in the case that the format information in NFC information represents " uncompressed bitmap ", select unit 43 selects to confirm via it One SSID of the traffic rate of 100Mbps or higher（I.e. one AP）.Meanwhile, the format information in NFC information is included in Represent the data form in addition to " uncompressed bitmap "（For example, " PDF " or " JPEG "）In the case of, select unit 43 is selected By a SSID of its traffic rate of the confirmation less than 100Mbps（I.e. one AP）.

Processing speed for processing the MFP10 of print data depends on the data form of print data.For example, for having There is the processing speed of print data of data form " uncompressed bitmap " higher than for the print data with data form " PDF " Processing speed.In the present example, in the case that the data form in print data is " uncompressed bitmap ", high pass is realized in selection Believe an AP of speed.Therefore, MFP10 can be while print data be received, with high speed processing print data, thus with high speed Printed matter is rapidly supplied to user.

And, in the present example, in the case where the data form of print data is different from " uncompressed bitmap ", selection is real One AP of existing low communication speed.If in the case of " uncompressed bitmap " is different from the data form of print data, A configuration of AP of traffic rate high is realized in selection, then print data receives speed and is changed to above print data processing speed. As a result, even if receiving print data, there is also the possibility that can not possibly rapidly process the print data.In view of these feelings Shape, in the present example, in the case where the data form of print data is different from " uncompressed bitmap ", MFP10 selections are realized low One AP of traffic rate.Therefore, it can suitably suppress only some AP has the appearance of event of big load.And, at this In example, for example, " uncompressed bitmap " and " PDF " are respectively the examples of the first data form and the second data form.

In step S117, control unit 70 is determined via NFC I/F62, if receive any AP from MFP10 Information.In the case where AP information is had been received by, control unit 70 skips step S118 to S122 and enters step S124.Tool Body ground, can not make portable set 50 add the WFD networks that are operated with G/O states of MFP10, or MFP10 currently to participate in MFP10 Normal Wi-Fi network in the case of（The step of Fig. 9, S141 was the situation of "No"）, be transferred to for predetermined response portable by MFP10 Formula equipment 50.Predetermined response is not include WFD wireless settings or normal Wi-Fi wireless settings but the sound including safety information Should.And, predetermined response can not include the null response of even any safety information.The receiving unit of portable set 50 81, via NFC I/F62, predetermined response are received from MFP10.In this case, control unit 70 is defined as in step S117 "No", and enter step S118.

In step S118, the method for S42 the step of the communication obtaining unit 84 of portable set 50 is by using with Fig. 3 Identical method, carries out SSID search.As a result, communication obtaining unit 84 obtains multiple PRes signals from multiple AP4a and 4b. In step S120, the select unit 83 of portable set 50 selects an AP from multiple AP4a and 4b.Select unit 83 first from The multiple SSID in multiple PRes signals are included in, one or more the participation information stored in memory 74 are extracted and be included in One or more SSID of one or more SSID matchings in.Then, select unit 83 is from one or more extracted SSID, one SSID is to select an AP for selection.Hereinafter, will be described in detail for selecting a specific side of AP Method.

In step S122, the method for S46 is identical the step of the transmission unit 82 of portable set 50 is by using with Fig. 3 Method, prepare AP information.Then, transmission unit 82 is via NFC I/F interfaces 62, by AP information transfers to MFP10.Carry in passing One, after transmitting AP information in step S122, control unit 70 is for example made to export pre- tone from portable set 50, For informing the control that the user of portable set 50 NFC communication has terminated.Therefore, user can appreciate that can make it is portable Formula equipment 50 is away from MFP10.The step of being carried out after step S122 in S124, the communication unit 86 of portable set 50 with it is selected AP carries out wireless connection.Step S117 be "Yes" in the case of carry out the step of S124 in, communication unit 86 by using from The AP information that MFP10 is received, carries out the wireless connection with AP.In step S126, communication unit 86 is by using the step with Fig. 2 The method identical method of rapid S20, via WLAN I/F60, MFP10 is transferred to by print data.

（The communication process of the MFP10 shown in Fig. 9）

The step of Fig. 9 S130 to S141 and S149 with Fig. 3 the step of S30 to S41 and S49 it is identical.In step S142, Predetermined response is transferred to portable set 50 by the control unit 30 of MFP10 via NFC I/F22.In step S144, control Unit 30 receives AP information via NFC I/F22 from portable set 50.The step of Fig. 9 S146, S150 and S152 and Fig. 3 Step S48, S50 is identical with S52.

（Example 4-1）

Then, by the content of the AP selection treatment of S120 the step of describing Fig. 8.The AP systems of selection of this example and example 1- 1 method is identical.That is, in the case where user determines to print data setting code（I.e. safety information represents safe feelings Shape）, select unit 83 select via its confirm " AES " a SSID（I.e. one AP）.Meanwhile, determine not fight each other in user In the case of print any password of data setting（I.e. safety information represents unsafe situation）, select unit 83 select via It confirms the encipherment scheme in addition to " AES "（Such as " TKIP " or " WEP "）A SSID（I.e. one AP）.

（The specific example of the example 4-1 shown in Figure 10）

In the sequence chart of Figure 10, it is assumed that the situation identical situation with Fig. 4.And, the memory of portable set 50 The 74 stored participation items of information corresponding with AP4a, and the participation item of information corresponding with AP4b.

Once receive predetermined response from MFP10 via NFC I/F62（The step of Fig. 8, S117 was "No"）, in step In S118, portable set 50 carries out SSID search.As a result, each reception PRes letter of the portable set 50 from AP4a and 4b Number.

In the situation " A " of Figure 10, password is set to print data（That is, safety information represents safety）.Cause This, in the step s 120, portable set 50 just uses the AP4a of encipherment scheme " AES " from multiple AP4a and 4b selections.Then, In step S122, via NFC I/F62 be transferred to the AP information for including the SSID " aaa " for representing AP4a by portable set 50 MFP10.Then, in step S124, portable set 50 carries out the wireless connection with AP4a, to add AP4a to be formed just Normal Wi-Fi network.Then, print data is transferred to AP4a by portable set 50 via LAN I/F60.AP4a is by print data It is transferred to MFP10.
